Answer:

The correct option is b: A solute depresses the freezing point because the solute disrupts the crystal formation of the solvent.

Explanation:

The depression of the solvent's freezing point is caused by the addition of a solute because the presence of the molecules of the solute interferes in the arrange and close up of the molecules of the solvent to form the crystal of the solid.

The attraction of the solute molecules to the solvent molecules interfere with the formation of the solid, so the solution must be cooled to a lower temperature so it can form the solid.

Hence, the correct option is b: A solute depresses the freezing point because the solute disrupts the crystal formation of the solvent. The other options are incorrect.

Answer:

Magnetic field, current and motion are mutually dependent.

Explanation:

Fleming's right hand principle explains that when any two of current, magnetic field and motion are available, the third would be induced. These three variable are mutually perpendicular to one another. This principle has its application in an electric fan which induces the motion of the blades due to flow of current and magnetic field in the coil.

In the simple circuit, the interaction between the flow of charges (i.e current) and the magnetic fields of the permanent magnet induced the motion of the wire.

The acceleration of [tex]25\ m/s^2[/tex] is produced in the person.

Explanation:

We have,

Mass of a person is 80 kg

Force acting on the person is 2000 N

It is required to find the acceleration produced in the person due to force.

The force acting on the person is given by :

[tex]F=ma\\\\a=\dfrac{F}{m}\\\\a=\dfrac{2000}{80}\\\\a=25\ m/s^2[/tex]

So, the acceleration of [tex]25\ m/s^2[/tex] is produced in the person.

Answer:

The acceleration of the object measured in [tex]\frac{m}{s^{2}}[/tex], as a function of time is equal to:

[tex]a = 18\cdot t[/tex]

Explanation:

The acceleration function is obtained by deriving position function twice:

[tex]a = \frac{dv}{dt} = \frac{d^{2}x}{dt^{2}}[/tex]

[tex]x = 3\cdot t^{3}[/tex]

[tex]v = 9 \cdot t^{2}[/tex]

[tex]a = 18\cdot t[/tex]

The acceleration of the object, measured in [tex]\frac{m}{s^{2}}[/tex], as a function of time is equal to:

[tex]a = 18\cdot t[/tex]

The period is  [tex]T = 13.53 \ sec[/tex]

Explanation:

From the question we are told that

     The length of the cable is  [tex]L = 45.5 \ m[/tex]

Let take acceleration due to gravity as [tex]g = 9.8 \ m/s^2[/tex]

Now the period of the oscillation is mathematically represented as

          [tex]T = 2 \pi \sqrt{\frac{L}{g} }[/tex]

substituting values

          [tex]T = 2 * 3.142 \sqrt{\frac{45.5}{9.8} }[/tex]

          [tex]T = 13.53 \ sec[/tex]

Answer: 13.53

Explanation:

Answer:

Explanation:

i) The total distance traveled will be the sum total of individual distances traveled by the man.

If the man travels a distance if 1.5 m towards east ,then 2m towards south and 4.5 m towards east, the total distance traveled will be expressed as; 1.5m+2m+4.5m

= 8.0m

ii) In order to get the man resultant displacement, we will use the Pythagoras theorem. Since the man travels a distance if 1.5 m and 4.5m towards east, the total distance taken towards east will be 6.0m and the distance traveled towards south is 2.0m. The resultant displacement of the man is expressed as;

R = [tex]\sqrt{x^{2}+y^{2} }[/tex]

Note that the eastward direction is the x-direction while the south direction is the y-direction.

x = 6.0m and y = 2.0m

[tex]R = \sqrt{6^{2}+2^{2} } \\R = \sqrt{36+4}\\ R = \sqrt{40} \\R = 6.32m[/tex]

The displacement of the man is 6.32m

Five workers from the same factory developed angiosarcoma, a rare cancer of the veins and arteries. This is observation of the scientific method.

Since at least the 17th century, the scientific method—an empirical approach to learning—has guided the advancement of science. Since one's interpretation of the observation may be distorted by cognitive presumptions, it requires careful observation and the application of severe skepticism regarding what is observed.

It entails developing hypotheses through induction based on these observations, testing the validity of those hypotheses through experimental and measurement-based statistical testing of the inferences made from them, and then fine-tuning (or discarding) those hypotheses in light of the experimental results.

These are the guiding principles of the scientific process, as opposed to a predetermined set of steps that apply to all scientific endeavors.

Answer:

-10.8°, or 10.8° below the +x axis

Explanation:

The x component of the resultant vector is:

x = 3.14 cos(30.0°) + 2.71 cos(-60.0°)

x = 4.07

The y component of the resultant vector is:

y = 3.14 sin(30.0°) + 2.71 sin(-60.0°)

y = -0.777

Therefore, the angle between the resultant vector and the +x axis is:

θ = atan(y / x)

θ = atan(-0.777 / 4.07)

θ = -10.8°

The angle is -10.8°, or 10.8° below the +x axis.

Answer:

Once you have drawn the free-body diagram, you can use vector addition to find the net force acting on the object. We will consider three cases as we explore this idea:

Case 1: All forces lie on the same line.

If all of the forces lie on the same line (pointing left and right only, or up and down only, for example), determining the net force is as straightforward as adding the magnitudes of the forces in the positive direction, and subtracting off the magnitudes of the forces in the negative direction. (If two forces are equal and opposite, as is the case with the book resting on the table, the net force = 0)

Example: Consider a 1-kg ball falling due to gravity, experiencing an air resistance force of 5 N. There is a downward force on it due to gravity of 1 kg × 9.8 m/s2 = 9.8 N, and an upward force of 5 N. If we use the convention that up is positive, then the net force is 5 N - 9.8 N = -4.8 N, indicating a net force of 4.8 N in the downward direction.

Case 2: All forces lie on perpendicular axes and add to 0 along one axis.

In this case, due to forces adding to 0 in one direction, we only need to focus on the perpendicular direction when determining the net force. (Though knowledge that the forces in the first direction add to 0 can sometimes give us information about the forces in the perpendicular direction, such as when determining frictional forces in terms of the normal force magnitude.)

Example: A 0.25-kg toy car is pushed across the floor with a 3-N force acting to the right. A 2-N force of friction acts to oppose this motion. Note that gravity also acts downward on this car with a force of 0.25 kg × 9.8 m/s2= 2.45 N, and a normal force acts upward, also with 2.45 N. (How do we know this? Because there is no change in motion in the vertical direction as the car is pushed across the floor, hence the net force in the vertical direction must be 0.) This makes everything simplify to the one-dimensional case because the only forces that don’t cancel out are all along one direction. The net force on the car is then 3 N - 2 N = 1 N to the right.

Case 3: All forces are not confined to a line and do not lie on perpendicular axes.

If we know what direction the acceleration will be in, we will choose a coordinate system where that direction lies on the positive x-axis or the positive y-axis. From there, we break each force vector into x- and y-components. Since motion in one direction is constant, the sum of the forces in that direction must be 0. The forces in the other direction are then the only contributors to the net force and this case has reduced to Case 2.

If we do not know what direction the acceleration will be in, we can choose any Cartesian coordinate system, though it is usually most convenient to choose one in which one or more of the forces lie on an axis. Break each force vector into x- and y-components. Determine the net force in the x direction and the net force in the y direction separately. The result gives the x- and y-coordinates of the net force.

Example: A 0.25-kg car rolls without friction down a 30-degree incline due to gravity.

We will use a coordinate system aligned with the ramp as shown. The free-body diagram consists of gravity acting straight down and the normal force acting perpendicular to the surface.

We must break the gravitational force in to x- and y-components, which gives:

F_{gx} = F_g\sin(\theta)\\ F_{gy} = F_g\cos(\theta)F

Since motion in the y direction is constant, we know that the net force in the y direction must be 0:

F_N - F_{gy} = 0F

=0

(Note: This equation allows us to determine the magnitude of the normal force.)

In the x direction, the only force is Fgx, hence:

Explanation:

Draw a free body diagram.  There are three forces on the block:

Weight force mg pulling down,

Buoyancy force B pushing up,

Tension force T pushing up.

Sum of the forces in the y direction:

∑F = ma

B + T − mg = 0

T = mg − B

Buoyancy is the weight of the displaced fluid:

T = mg − ρVg

The block is fully submerged, so the volume of displaced fluid equals the volume of the block.  The volume of the block is its mass divided by its density.

T = mg − ρ (m/ρₓ) g

T = mg (1 − ρ/ρₓ)

Plug in values and solve.

T = (0.5 kg) (10 m/s²) (1 − (1000 kg/m³) / (8000 kg/m³))

T = (5 N) (1 − ⅛)

T = 4.375 N

Peter Medawar, a Nobel Prize-winning biologist, once described scientific inquiry as "the art of the soluble"  In order to succeed in science, one must first identify the questions that may be answered by scientific study and then determine the answers to those questions, according to Medawar.

Because of how intricate the natural world is, it is frequently impossible to directly address the really intriguing, significant scientific topics

The art of science includes repeatedly re-imagining these complex issues, mentally dividing them into more manageable components, and then guessing as to which of these more manageable components might hold the answer to solving the larger issue.

Therefore, all the discoveries and inventions are resulted from the creative ideas and thoughts of scientists. Therefore, creativity is the only way to make a controlled experiment.
